class System
{
    private static ?System $instance = null;

    static public function getInstance(): System
    {
        if (self::$instance === null) {
            self::$instance = new self();
        }

        return self::$instance;

The expression return self::instance could return the type null which is incompatible with the type-hinted return Startwind\Inventorio\Exec\System. Consider adding an additional type-check to rule them out.
